STOVE.

SPECIFICATION forming part Of Letters Patent No. 705,928, dated July 29, 1902.

Application filed March 4, 1902. Serial No. 96,586. (No model.)

To aZZ whom it may concern:

a citizen of the United States, residingat Sedalia, in the county ot.Pettis and State of Missouri, have made certain new and useful Improvements in Stoves, of which the following is a specification.

My invention is an improvement in stoves, and relates particularly to the means for forcing the circulation of the products of combustion in order to secure the maximum heating results therefrom; and the invention consists in certain novel constructions and combinations of parts, as .will be hereinafter described and claimed. v

In the drawings, Figure 1 is a side view, and Fig. 2 an end view, of my stove. Fig. 3 is a cross-sectional view on about line 3 3 of Fig. 1. Fig. 4 is a horizontal section on about line 4 et of Fig. 1. Fig. 5 is a vertical longitudinal section on about line 5 5 of Fig. 2. Fig. 6 is a detail sectional view illustrating the valve controlling the direct communication between the combustionchamber and the ofitake; and Fig. 7 illustrates a somewhat different construction, as will bedescribed.

My stove, as shown, includes the combustiomchamloer or fire-box A, in which is supported the grate A, arranged to form the ashbox A and mounted upon the legs A to which is secured the shield-plate A whose ends are bent at A to form foot-rests or-for other desired purposes. A lateral extension B of the ash-box forms a draft-chamber, having inletopenings B, controlled by the damper B which may be adjusted longitudinally to regulate or shut off the passage of air to the ash-box and thence tothe combustion-chamber. A plate 0 is secured at its upper end 0 and extends thence into the ash-box over and slightly spaced apart from the opening b, which leads into the draft-chamber and tends to prevent any ashes from dropping into the draft-chamber when the stove is in use. A fine D extends longitudinally along the top of the combustion-chamber and communicates therewith through a central opening D and also by an opening E with the offtake E, the openings D and E being preferably in alinement, as will be understood from Figs. 3 and 5. A valve F, having ahandle F, controls the opening D and may pose.

be adjusted, as shownin Fig. 6, to close said opening, and thus prevent the products of combustion frompassing from the chamber .A directly to the ofttake.

when the sections G. and H are adjusted for use, and the section His provided with a door I hinged at I and latched at I and through which access'may be had to the interior of the combustion-chamber for any desired pur- These'sections G and H are provided with flues g andh, which extend around the edges of the sections and practically encircle the combustion-chamber at the ends thereof,

such flues at their inner sides at g and h being exposed to the action of the fire within the combustion-chamber, and nipples g and h connecting the flues G and H with the opposite ends of the top flue D, as shown in Fig. 5. At their inner sides near their upper ends the sectionslG and H are provided with openings 9 and 71. through which communication is established with the interior of the stove, so the products of combustion pass through the openimgsg and 71. into the flues g and h and will be caused to circulate around through said flues by means of stop-plates g and h, which prevent the passage of the products through the openings 9 and 72, directly to the nipples g and h Thus in operation if the valve F be closed the products of combustion will be caused to pass through the openings g and 77, into the end flues and circulate around through said flues and discharge through the nipples g and it into the ends of the top fiue and pass thence out through the offtake.

As shown in Figs. 1, 3, and 4,. the combustion-chamber has a side door K, arranged immediately above' the draft-chamber B, which may be opened for any desired purpose.

It will be noticed from Figs. 2 and 3 that the end flues are made oval with the major axis vertical and parallel with the corresponding axis of the oval combustion-chamber; but manifestly such flues and chamber may be made round in cross-section or may be made diamond shape, as will be understood from Fig. '7, which shows a diamondshape arrangement of the end flues. The end-flue sections may preferably be. hinged, as shown, to facilitate access to the stove and to the interior of the flues through the openings g and h but it will be understood that where desired they might be made fast with the combustion-chamber and to operate as before described.

While I refer to the flue D as the top flue it will be understood that it need not be arranged at the extreme upper side of the combustion-chamber, but may, if desired, be located down alongside of such chamber, it being understood that this so-called top flue receives the double-actin g heat which is drawn through both encircling end flues, as before described.

Any suitable fuel may be used in the stove.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The improvement in stoves herein described, comprising the combustion-chamber or fire-box having an outlet-openingin its top, a top flue communicating with said opening and extending from end to end of the combustion-chamber, the offtake connected with said flue, the grate within the combustionchamber, the draft-box below said grate and lateral to the combustion-chamber, the damper controlling said draft-box, the plate Within the ash box and overlying the opening between the draft-box and the ash-box, and the end sections having encircling flues provided with stop-plates and on one side of said stopplates with nipples arranged to enter the opposite ends of the top fine and on the other side of said stop-plates with openings leading into the combustion-chamber, all substantially as and for the purposes set forth.

2. The combination in a stove with the combustion-chamber and the top flue extending along the same and provided with an opening communicating with the co'mbustiomchamher and with a valve controlling said opening, of the sections at the ends or the combustion-chamber and provided with encircling fines each having a stop-plate and communicating on one side thereof with the end of the top flue and on the other side of said stop-plate with the interior of the combustionchamber, substantially as and for the purpose set forth.

3. The combination in a stove with a combustion-chamber and a top flue, of the end sections hinged to the combustion-chamber and having encircling flues and nipples connecting the same with the opposite ends of the top flue, and having stop-plates and openings in the end flues, whereby the products of combustion from the combustion-chamber may be caused to circulate through the end flues and thence into the top flue and an off take connected with the top flue, substantially as set forth.

4. The combination with the combustionchamber, and a flue extending along the top thereof, and communicating at its middle with the combustion-chamber and having at its middle an offtake, of a valve controlling the communication between the top flue and the combustion-chamber, and the end sections having encircling flues arranged to receive the products of combustion from the combustiOn-chambenand to discharge such products to the opposite ends of the top flue, substantially as set forth. I

5. The combination with the combustion chamber, of flues encircling the opposite ends of the combustion-chamber and having openings through which to receive the products of combustion from the combustion-chamber, and an ofttake in connection with said flues, substantially as set forth.

6. The combination of the combustion chamber, the end sections having flues encircling the opposite ends of the combustionchamber, a top flue in communication at its opposite ends with the opposite end flues, a door in one of the end sections, and a valve controlling direct communication between the top flue and the combustion chamber, substantially as set forth.
